Setting QAbstractSocket::LowDelayOption option via QAbstractSocket::setSocketOption() has no effect if called before QAbstractSocket::connectToHost().
`example1()` silently ignores setting `QAbstractSocket::LowDelayOption` and produce syscalls as attached in appendix log1.txt. On the other hand, `example2()`seems to work (see appendix log2.txt)
Actually, the documentation contains a hint, that `QAbstractSocket::KeepAliveOption` must be set before the socket is connected when running on Windows Runtime. In my opinion, setting an option via `QAbstractSocket::setSocketOption()` should be always possible and independent if the socket is already connected, connecting or idle. POSIX API also allows to configure socket options before establishing a connection.
